' IMPROVEMENT IN FANNING-MILLS,

Specification forming part of Letters Patent No. 46,3l2, dated February7, 1865.

To all whom it may concern Be it known that I, HENRY W. VEREGGE, ofRichmond, in the county of Wayne and State of Indiana, have invented anew and use ful improvement in the manner of hanging the slides orwind-hole shutters of fanning and other wind mills; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being bad to the accompanying drawings, making apart ofthis specification, in which- Figure 1 represents the side of afanningmill. Fig. 2 represents a vertical transverse section through thesame, taken at the red line .70 w of Fig. 1.

Similar letters of reference, where they occur in the separate figures,denote like parts in both.

The slides or wind-hole shutters of fanningmills are generally hung ingrooves made in or by two horizontal pieces,one at the top and the otherat the bottom of the shutter. This mode of hanging the shutters isobjectionable on several accounts-first, the accumulation of dirt, grit,&c., in the grooves prevents them from sliding freely; second, if madeto slide freely originally, they will not remain at any fixed positionwithout fastening them, the jar of the machine moving them one way orthe other; and, thirdly, if made to Work close, then the least swellingor warping of the wood so binds them as to prevent them from moving atall. I am aware that to obviate these objections to this general plan ofhanging the slides holes have been bored through the shuttershorizontally, for the reception of a rod or bar, upon which the'shuttermay be slid. Though this answers a good purpose, it is difficult andexpensive to make and repair, for unless the rod or bar be heavy enoughto sustain the shutters without sagging, which of course involves themaking of the shutters thick enough for the necessary hole to slide overthe bars, it will not work well and smoothly. Besides, with this roundbearing there is nothing to keep the shutters close up to the side ofthe machine and make them what they are designed to be-namely, wind holeshutters.

I make no reference to that kind of shutters that swing from a pivotedpoint, as they will not open the whole windway when necessary, and donot come within the scope of my invention.

My invention consists in making a horizontal groove in a piece attachedto the side or frame of the fanning or other wind mill, and making astrip, rib, or batten on the'slides or shutters that will freely move insaid groove, so that the slides or shutters are suspended by the stripor rib, and are kept in place close up to the side of the mill by thepiece on which it moves.

To enable others skilled in the art to make and use my invention, I willproceed to dc= scribe the same with reference to the drawlngs.

A represents one of the sides of an ordinary fanning-mill; and B,theopenings thereof, leading into the fan or fan-case, for supplying thefan with air to make a regulated blast.

O O are the slides or shutters for par tiall y or entirely closing theopenings B, as may be found necessary. These shutters or 'slides I hangas follows: In the piece D, I

form a groove, a, (rectangular or otherwise,) in that face of it next tothe side A of the mill, and upon the shutters or slides G, I fasten astrip, rib, or batten, c, that will freely move in and through saidgroove a. This strip, rib, tongue, or batten may be as long as theshutters have width, or they may be blocks or cleats, but so made as torun in the the groove, and with rigidity enough to hold up the shuttersor slides, which, moving between the piece D and the side A, is kept inproper position as it is moved along. This device is cheaply made andeasily attached, and any farmer may easily and readily repair it. Thegroove a, being horizontal instead of vertical, catches no dirt or gritto clog the movement of the slides. The slides move freely and easily,yet will remain in any adjusted position within the limits of theirmovement. If desirable, the groove may be dovetailed, and the tongue orpiece or pieces that slide in it may be of a corresponding shape orform; 4

Having [thus fully described my'invention and shown wherein it differsfrom what has ters and a horizontal groove or grooves in the beenhitherto known for a similar puspose, face of said frame or piece, asand for the purwhat I claim therein as new, and desire to sepose setforth. cure by Letters Patent, is-- Hanging the slides or shutters 0ffanning or other similar mills t0 the frame, or to a Vituesses: piececonnected to the frame, by means of a LEWIS D. STUBBs, tongue, strip, orblock on said slides or shut- WILLIAM: BARR.
